01Mechanism of Action
Parameter
DSIP
Semax
Primary target
Multiple — modulates HPA axis + thalamic delta-wave generation (proposed)Schneider 1986
BDNF / NGF expression + monoamine modulationKaplan 2017
Pathway
Reduced cortisol/ACTH + enhanced delta-wave EEG activity → improved sleep onset + depthSchneider 1986
↑ BDNF + NGF synthesis + 5-HT modulation → neuroplasticity + anxiolysis + cognitive enhancementKaplan 2017
Downstream effect
Faster sleep onset, increased delta sleep, reduced stress response, possible anxiolytic effectSchneider 1986
Improved memory + attention; reduced anxiety; neuroprotection in ischemiaKaplan 2017

05Administration Protocol
Parameter
DSIP
Semax
1. Reconstitution
Add 1–2 mL bacteriostatic water to vial.
Pre-formulated nasal spray (commercial) or research vial reconstituted with bacteriostatic water.
2. Injection site
SQ — abdomen. Rotate sites.
Intranasal — 2–3 sprays per nostril per dose. Tilt head slightly back.
3. Timing
30–60 min pre-sleep.
Morning + early afternoon. Avoid evening (sleep disruption).
4. Storage
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
Refrigerate after reconstitution; light-protected.
5. Needle
29–31G insulin syringe.
Cycle on/off to avoid neurochemical adaptation.
06Stack Synergy
DSIP
— no documented stacks
Semax
+ Selank
ModerateSemax (cognitive enhancer, BDNF/NGF) and Selank (anxiolytic + immune) form the canonical Russian "neuro stack" — both intranasal peptide bioregulators with complementary axes. Semax for cognitive demand; Selank for stress mitigation.
- Semax
- 200–600 mcg intranasal · morning + afternoon
- Selank
- 150–300 mcg intranasal · midday + early evening
- Primary benefit
- Cognitive enhancement + stress mitigation
